Small devices need to handle a mixture of wireless radio standards

Intel is researching multi-radio technology in an attempt to enable adaptable
and power-efficient radio technology.

Krishnamurthy Soumyanath, director of the Communications Technology Lab at
Intel, spoke about the 'radio evolution' at the Intel Developer Forum in
Shanghai.

The company has achieved "significant milestones" in developing low-cost
digital multi-radios that will connect the mobile devices of the future.

The essential premise is to allow small devices to handle a mixture of
wireless radio technology standards from just one chip that consumes less power
than today's bulky analogue versions.

Soumyanath explained that the platform consists of three distinct elements:
the processor; the IO controller; and the radio chip.

However, having these as separate components adds complexity, cost, size and
power consumption.

In order to create a smaller silicon footprint, with less power consumption,
lower cost, fewer connections and less complexity, these discrete components
need to be integrated into a single platform-on-chip.

Two prototypes were showcased during the IDF presentation. The first is a
multi-band, power efficient CMOS transceiver that incorporates earlier digital
wireless communications research.

The second is a power amplifier combined with a spectrum sensing
analogue-to-digital converter.

Soumyanath acknowledged many hurdles that need to be overcome in order to
seamlessly connect the next generation of mobile devices if manufacturers want
to meet the growing connectivity and longevity demands of their customers.
